Grains of Nontraditional Crops as Sources of Retrograded Resistant Starch

摘要

The content of retrograded resistant starch of the RS_3 type was determined in six plant species and their accessions. Besides sorghum and foxtail millet, plant genotypes were cultivated in Piestany locality in the year 2003. There were significant differences in RS_3 and total starch content in analysed crops and their accessions. Chickpea and buckwheat had the highest average content of RS_3, 5.2% and 3.8%, respectively. Millet and foxtail millet contained less RS_3, 2.9% and 2.8%, respectively. Millet was rich in total starch. The lowest amounts of RS_3 were detected in sorghum (1.6%) and amaranth (1.2%). The lowest variation in the RS_3 content was detected within the set of millet accessions and the highest within amaranths.
